C Programming Tutorial - 7 - More on Loops

[edwinsai]

How About NESTED LOOPS?

[tadm123]

What if you want 30 lines to appear? (note : lines, not the actual value) What funciton do you use?

[bondservant4Him]

@tadm123 you need a loop

[tadm123]

How can i program it so the user is the one who enters the increment he wants?

[taetantantan]

hey buck well so im new to this stuff, have you made any videos involving 'harder' combination problems? by combination i mean like all of the past videos combined like switch-looping or something.

[MrVidposter101]

OR

counter++; does the same thing but shorter

[harlytrav]

@MrVidposter101 He did say counter++. Though counter++ only adds 1

[MaxOp1234]

the people that disliked this clearly have no f**king idea what hes talking about but other than that HOW COULD YOU NOT LIKE THESE THINGS HE IS TEACHING YOU I MEAN REALLY COMEEEE ONNNNN!!!!!!

[young2theb]

Hey Bucky this is totally unrelated to the matter at hands but which do you prefer macs or pc?

[alaax4max]

thanks. thanks.thanks.thanks.thanks.th­anks.thanks.thanks.thanks.than­ks.thanks.thanks.thanks.thanks­.thanks.thanks.thanks.thanks.t­hanks.thanks.thanks.thanks.tha­nks.

[TheChatbug]

He still has wooping cough, poor guy.

[LightningHexagon]

*N numbers

[LightningHexagon]

Here's a simple exercise:

Write a program that allows the user to enter N number then calculate the

arithmetic mean.

PS: pm for code

[ShakkIsLife]

Woops, I replied before watching the video.

[ShakkIsLife]

@0121ryanh117

Or to increment by 1, use

'variable++'

[WinXPproff]

Thanks a lot!!! Its realy helpfully.

[TheAplteam]

And can i don`t use 3 arguments?

[DJGPR2]

i want to make a program on which the user enters the number with which the counter starts and ends. i have done the printf and scanf functions (like ''type the first number:",''type the second number:'',scanf("%d", number1),("%d", number2).

thanks in advance. please post additional instructions.

[mokaey]

for(counter = 1;counter < 99999999;counter++){ 

[mmaassiikk]

Thanx a lot ! Love you ,man !

[giannamarielanete]

thnx :D

[alexpunisher143]

what softwre did u use ?? please reply .. I would like to use the same program instead of using the blue screen... thanks.. hope to get a reply.. :)

[Ticomfreak]

@alexpunisher143 he used dev C++

[IEOA]

@alexpunisher143

He was using Dev C++ here.. but I would recommend Code::Blocks instead because Dev C++ uses old/outdated compilers that do not follow current standards.

[joelvis65]

hes using dev c++ ..its good but not the best... the "blue screen" wat u referred to is turbo c.. its quite good... but a bit erratic sumtyms.. id suggest u use turbo c++ compiler.. its damn good

[amh171]

thanks a lot..i need some help from you. can you explain to me what this code dose? void main() { int i,j; printf("\1\n"); for ( i = 1; i <= 10; i++ ) { for ( j = 1; j <= i; j++ ) printf("%c%c",97,97); printf("\n"); } } ..why every time it has new line, there is another 2 extra a's from previous line?

[angelprincessgal]

i also got a problem that my program didnot execute

it give error code that is stdio.h file don`t find pls help me

i

[angelprincessgal]

hi

i wanna ask u something..

how we make a program that give the factorial of the given number

[lDeadLoss]

Hey, why is it that in C++ we can do for(int i = 0; i < 10; ++i) and int C we cant? We have to do int i; then do our for loop.

[BulletForMyTeachers]

I suspect your name is Greg but not Bucky... B)

Am I right? lol

I love them both :)

[chrostop]

it is great

[phunagewine]

bucky for life!

[allpogi]

ty for teaching i got it a little now

[whymeproducz]

great tutorials even though i take a C course u teach better than that other lame teacher i got lol 5/5!!!

[toolband79]

Bucky, you're great at doing these tutorials keep it up.

[AutoRijeka]

Great tutorials, it's very easy to follow

[msatrakkoic1]

Bucky, youre amazing. In lecture my prof took about 6 hours to do loops, and you managed to make it easier in just over 6 minutes. Big help. Keep it up!

[DhDo74]

Thanks Bucky, I had problems learning about for loops from my professor and you cleared it up for me!

[stonechime18]

is there other syntax in the counter++?? how bout i want it to increment by 2.?

[shoofeer1]

I was thinking about just that a while ago....I think the "++" operator is only used when you need to increment by 1. for incrementing by 2, you would need to use counter+=2, or counter=counter+1.

[DIABLOVT12]

@shoofeer1 Correct. ;)

[abujp1993]

mybe then u have to use like skip 2 or something

i dont know exactly

[bboybram]

int counter = 0

should make it 0 3 6 9 instead of 1 4 7

I get it ... these videos really help a lot.

[lmiies]

Thank you

God bless you

[magombre]

it will be nicenot to put  20 but 100000000000000000000000000

LOL XD

[saxyd33]

im usually a lazy as.s but dam today im learning and acutally getting it all

[luileth]

bucky..!!!

you're a big help!!

thanks.... :)

[davidspiteri77]

@luileth he is a huge help i agree

[larile14344]

thanks BUcky. awesome.

[akcire6]

Buckey can you do a tutorial on nested while loops?

[shad79]

i run the above code exactly the way he said and i get 2293572

it doesnt make sense i have no idea why can someone help me please??

[sandorlev]

it has something to do with the

printf("%d\n", counter);

part!

[shad79]

and how can i solve it?

[sandorlev]

just try it again, and if it's still wrong, leave it as it is. maybe next time at a different program, you'll make it. just don't panic if you don't understand sg. you can learn it later, don't need to rush...

[ferozkumar]

Which compiler is he using. I am now using turbo c and i want to install also this can i use both without any fluctuations?

[woyzz128]

He is using DevC++, if Im not mistaken. You can Google it.

[amh171]

hi..what should I type inside the "scanf" if i want the user to enter the letter instead of number. for example..

printf("Do you want to repeat the process,y/n ?");

scanf();

thankyou.

[simeesta]

scanf("%c",&character);

[paulpartdude]

how about usng "%c", in loop can you do that

[ducktails57]

no you cant do that

%d is a place hold that will be replaced with the value of the integer (counter)

if you use %c the character value is expected which is not a number

[bw800402]

also i noticed that it is uneccessary to declare a value for counter other than in the for statement.

[bw800402]

why is it necessary to put counter =1; in the for statement before counter <20? It seems to me counter < 20 should take care of that. I tried to exclude counter = 1 and errors.

[dave422x]

for needs three arguments

[pliskinn0089]

but you have infinite negative numbers it would be crazy to no specified. i tried to exclude it too but it dint work.

[MasterMind300]

I didn't know that. counter is easier lol
